Specification of Letters Patent.

CORN-SHELLER.

Patented July 21, 1914.

Application filed. August 14, 1912. Serial No. 715,088.

To (ZZZ whom it may concern Be' it known that 1, JOHN KIovsKY, a citizen of the United States, residing at As toria, Long Island, in the county of Queens and State of New York, have invented new and useful Improvements in Corn-Shellers, of which the following is a specification.

This invention relates to corn shellers, and it has for its object to produce a simple and eflicient machine of this class which shall be double acting, that is to say, which shall be provided with two hoppers for the reception of ear corn, and earn projecting pistons operating alternately in said hoppers.

A further obj ect of the invention is to provide shelling chucks or heads of simple and improved construction for'removing the kernels from the ears as they are being projected from the hoppers.

A still further object of the invention is to simplify and improve the construction and arrangement of the operating mechanism of the device.

lVith these and other ends in view which will readily appear as the nature of the invention is betterunderstood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out/in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired. v

In the drawings, Figure 1 is a top plan view of a machine constructed in accordance with the invention. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal vertical sectional view taken on the line 33 in Fig. 1. Fig. 4 is a rear end elevation. Fig. 5 is a front elevation of one of the shelling heads or chucks detached. Fig. 6 is a sectional View through said head takenon the line 66 in Fig. 5.- Fig. 7 is a sectional detail of the outer end of one of the shelling members. Fig. 8 is a detail view of one of the ear engaging members.

Correspondmg parts in the several figures are denoted by like characters of reference.

The frame 1 of the improved machine, WhiQh i5 Of Substantially rectangular shape,

maybe provided with legs or supporting members 2 at the corners thereof. Said frame 1s provided adjacent to what'will be regarded as its front end with bearings for a main driving shaft 3 whichmay be rotated by hand, by means of a suitable crank,

or by power derived from any suitable source. The shaft 3 is provided with cranks 4, 4.

The side members of the frame 1 are provided with downwardly extending brackets 5 supporting a transverse shaft o. .Fulcrumed upon the shaft 6 are levers or arms 7 which are connected by means of links 8 with the cranks 4: on the driving shaft 3. The cranks 4 are disposed to project in diametrically opposite directions, and the swinging movement imparted to the two levers 7 will thus be in opposite directions. The frame 1 supports upwardly'extending brackets 9 that extend across the frame and are provided with bearings 10 wherein two piston rods 11 are mounted slidably for re.-

ciprocation, said piston rods being disposed in substantially parallel relation to each other. Each of the piston rods 11 carries a boxing 12 engaged by an anti-friction head 13 on one of the arms orlevers 7 so that when'said arms or levers are operated by means of the drivingshaft 3 and the connecting rods 8 the piston'rods 11 will be reciprocated in opposite directions.

Suitably mounted on the frame adjacent to the rear end of the latter are hoppers 14 which are of such dimensions as to accommodate a single ear of'corn of average size "lengthwise therein, each hopper being preferably made of suitable dimensions t-o accommodate a tier or stack of from six to eight ears of corn. Each of the hoppers has a foraminous bottom; 15 through which grains of corn that become detached from the ears within the hopper may pass to a discharge chute 16. Therear-wall of each hopper is provided adjacent to the bottom thereof with'an opening 17 of suitable dimensions to admit of the passage of a single ear of corn. Supported on the frame 1 in rear of each of the hoppers 14: is a shelling head or chuck consisting of a casting 18 having feet 19 for the passage of fastening members, such as bolts 20. Each of the shelling heads has a central aperture 21 for the passage of the cob, and each of said heads is provided on the front and rear sides thereof with radial grooves 22' and. with caps 23 which are bolted or otherwise secured adjacent to said grooves and which coeperate with said grooves to form guideways for the shelling members 24. It will be observed that the; front side? or face of each chuck or through slots 27 in the caps 23. The stem of each shelling. member has a longitudinal bore or recess 28" wherein is placed a spring 29 serving toactuate the shelling member in an: inward direction, said spring being compressibl'eby a set screw operating through a lug. 81. formed at the outer end of thegrooveor guideway wherein the shelling.

member operates. It will be seen that by means of the set screws the pressure of the p shelling. members in the direction of the ears so or regulated-. It will be seen that the arouate'; jaws of t'he shelling members on the rear side ofeach head or chuck; will overlap the gaps between thearcuate jaws of the shelling members on the frontside of such chuck, thus causing the entire circumference of an ear of corn that is projected through the aperture21 to be engaged by the jaws of the shelling members.- Shields or guards 82 40 may be arranged between-the: rear walls of the hoppers andthe tront' faces of the heads or chucks above the central apertures of the tte Eachof the piston rods carries an ear en gaging. head 33, the same being; loosely con nected therewith by means ofsprings 34.. The-head of each pistonrod is adaptedto engage the lowermost ear in the respective hoppers, and to project the same throughthe apertures 17 in the rear walls of the hop pers a ndthrough the apertures 21 of the shelling heads, thereby eausing. the seeds to be removed from the cots, which letter drop '1 I1 rear of the frame oh the machine while 1 the seeds: are discharged over the chute 1 6 ijaws- 25'. of the heads 33 extend. beyond the lower portions thereof as shown in Fig. 8 and consequently the ends of the ears which are engaged by the heads 33 are prevented from into some suitable receptacle provided for the purpose. Theheads 33 are provided with bell mouthed ends which engage the ears and consequently the ears are moved with their axes approximately in alinement with the center of the opening between the Furthermore the upper portions tending to move in an upward direction as j the ears are forced between the jaws 25. At 1 the same time the said ears can not move in .a downward direction for the reason that they are in contact with the bottom 15 of the hopper.

rom the foregoing description taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood. lVhen the machine is operated by power, the hoppers may be fed by one man, and the operation of shelling the corn will be quickly and efficiently performed. In the absence of mechanical power, the machine may be manually driven by an additional operator.

Having thus described the invention, what e 1 is claimed as new, is that are to becperated uponmay be gaged 1 In a corn sheller, a hopper having an opening inits side, a shaft mounted for reciprocation in the hopper in almement with the opening. and a spring pressed head slid- ;abl y mounted on the shaft, and having abell mouthed end portion which normally ;l ies in advance of the end of the shaft and gwhichis adaptedv to resiliently present the ears of corn to'the sheller.

2. In a corn. sheller, a. hopper having an opening in its side, a shaft mounted for re ciprocation in the hopper in alinement with the opening and a spring pressed head slidmounted upon the shaft and having a ,bell mouthed end portion which normally lies-in advance of the head of the shaft and which isadaptedto resiliently present the e ars of corn to the sheller, the upper part of the said bell mouthed portion extending beyond the lower part of thesame.

In. testimony whereof I aflix my signature ;in presence of two witnesses.
